1'0 all whom, it nmy concern.- v

Be it known that I, CHARLES E. SCHMUNK, a resident of Pittsburg, in the county of Allegheny-and State of Pennsylvania, have in-- vented anew and useful Improvement in Apparatus for the Manufacture of Articles of lowing to be a full, clear, and exact description thereof. l

My invention relates to machines for manna facturing articles of glassware, such as lampchimneys, bottles, &c.

The object of my invention is to provide a form of apparatus by the use of which lampchimneys, bottles, and like articles can be made withgreat speed and accuracy without the aid of skilled labor,--whereby the articles may be produced ingreat quantities and at less cost.

My invention compris'es, generally stated, a suitable framewith a mold-support mounted as thatfor revolvingthe mold-support, being operated by the act of closing and opening the mold, all of which will be more'fully herein- To enable others skilled in the artto make more fully, referring to the accompanying drawings, in which Figure 1 is a front view, partly in section,

view of same. -Fig. 3 is aplan view, partly in section. Fig. 4 is a perspective view of the mold-support. Fig. 5 is a detail.- Likeletters'indicate like parts in each of In the accompanying drawings I have illusof lamp-chimneys; but 1 do not wish to be understood as limiting myself in any manner to the use of my machine for making any particular article, but wish to include within its scope all other articles which it maybe found expedient tofmake by the use of said machine. The letter 'A- designates a suitable frame upon which -the apparatus is mounted. Mounted in the frame A and adapted to revolve therein is the mold-support B' said illustratedfbein'g.

rectangular in form and liavi ngthe platforms 1) 11' b ll Any other suitable construction of the mold-support, however';maybe employed.

The mold-support B has the diagonal braces B, which set-veto strengthen the support.

. Projecting from the side of. the central boss or hub 13'' is the shaft 0, said" shaft being journaledwithin the journal-box c, bolted to the frame A- and supported thereby. At the outer end of the shaft 0 is mounted the pinion o Each of the platforms 1) b 12%? has a circular plate (I, fitting within a recess in said plat-' form',the upper face of said circular plate hav'.*

ing a dovetail (1' formed thereon, adapted to en gage'with a dovetail recess e in the bottom e of the partible moldE. This partible mold E, which in this instance is a lamp-chimney mold, is formed of the two halves hinged to-v7o' gether by means of the pin o which passes through the lugs e, formed on each halfof .said mold. A'spring f encirclesthe pin c",

the ends of said spring being secured to the halves at f, the action of said spring being to hold said halves normally open. into the circular plates d are the studs g, which carry the bevelpinions g. These bevel-pinions g mesh with like bevel-pinions h, mounted on the short shafts h', which are Threaded mounted in bearing-blocks h on the inside of the mold-support B. Clutches h having the conical clutch? recesses h, are mounted rigidly on the shafts-h. Mounted in bear-. ing's'i in the frame A issthe clutch c, said clutch 11 being always in position to engage with one of the clutches h when one of themolds is in position for operation. The

lclutch-shaft i has the annular groove i formed therein. Studs H on the bifurcated arm is engage the annular groove 4. at opposite points, said bifurcated arm 74 being se- 1 cured to the vertical shaft Z. This vertical shaft Z is journaled within suitable bearings l in the bracket A secured to the frame A. Secured to the upper end of the shaftl is the curved arm on, said arm having the curved slot m formed therein. n engages with the curved-slot m in the arm m. This lover, a is rigidly secured to the stud o, journaled in theframe, said Biilldhfln ving the bevel-pinion of .-.,mounted thereon. Theiouter end of the lever n has the idlea' mountedtherein, said idle-roller be A stud 'n. on a lever loo shaft p by the ordinary groove-and-feather connection, whereby the clutch-shaft 1? is free to slide back and forth on said shaft but rotates with the said shaft This s aft p is journaled within suitab e bearings A on the bracket A, andthe outer end of said shaft has the cone-shaped frictional head 1. vertical power-shaft s, driven by any suitable power, has its upper end journaled in bear-- ings in the bracket A, and secured to said shaft s are the cam-disks s and 8', said disks having the cam-faces s s, respectively. The disks 8' s are so arranged on the shaft .9 with reference to each other that the cam-faces s s are brought alternately into contact with the conical frictional head 1' of the shaft p.

In this manner by the rotation of the shaft 8 the cam-disks s .5 by means of their camfaces .9 s, impart a partial rotary movement to the shaftp in one direction and then in the opposite direction, as will more fully hereinafter appear. The bevel-pinion o meshes with a bevel-pinion t on the shaft 15, journaled in suitable bearings in the frame, the opposite end of said shaft t having a bevel-pinion t, meshing with a bevel-pinion t on the shaft i, said shaft t having at its opposite nd a bevel-pinion t meshing with a bevel-pinion t on the shaft F. The shaft t has at its opposite end bevel-pinion t meshing with the bevel-pinion t on the stud t journaled in suitable bearings in the-frame. To this stud t is secured the lever u, said lever having the friction-roller u at the inner end thereof corresponding to the idle-roller n of the lever n and engaging with the bottom plate e of the mold at the opposite'side from that of the lever n. By the above-described gearing mechanism any movement imparted to one of the levers n or u will impart like movement to the opposite one. The pinion t meshes with a pinion 12, mounted in suitable hearings in the frame, said pinion having the arm '0' secured thereto. The outer end of the arm 0' is connected by the link or strap 1; with the arm n, secured to the shaft 10', upon which is mounted the gearwheel w. This gear-wheel w meshes with the gear-wheel 0, before referred -to. At proper intervals on the outer face of the gearwheel 1'0 are the seats w, said seats having their bottoms inclined and adapted to receive the spring-latch a: on the arm 1;. 4 latch a: fits within a suitable socket 2: on the arm '0, and a spring is interposed between said latch a: and the socket m, whereby said latch is forced normully into contact with the face of the gear-wheel w or into the seat w, according to the position of the arm 0 as will more fully hereinafter appear. Extending up from the frame A is the upright rod y, said rod having the arms y at suitable intervals, said arms having the bosses y formed with semicircular seats adapted to receive a portion of the pipe II and serve as a support and guide for the same during the blowing operation. One'of the arms 1 has a slot y formed therein, through which the clamping-jaws y pass, said jaws being normally closed by the spring y", interposed between the outer ends of said jaws. These jaws y are pivoted at 1 and they tend to grasp and hold the pipe and steady it during the blowing operation. The upper'end of the pipe enters the scat z, formed at the outer end of the uppermost arm 1 This arm has the passage 2' passing through and connecting with the air-passage of the pipe. A suitable packing-ring z" surrounds the outlet of the passage 2'. A pipe z communicates with the passage 2, said pipe being connected with suitable device for supplying air for the blowing operation. \Vithin the frame A, in the lower portion thereof, is the tank or vessel 0, adapted to contain suitable cooling fluid.

I do not wish to limit'myself to the exact construction shown, as that may be modified without departing from thespirit of my invention.

The operation of my apparatus in the blowing of a lamp-chimney is as follows: With the parts in the position shown in Fig. 3 the mold-support B will have one of its moldsupporting platforms in proper position with reference to the frame for the blowing operation, and with the levers n and u in the positions shown in said figure the mold will be open and held open by means of the spring f. The gatherer gathers sufficient of the molten glass on the end of the pipe II and adjusts said pipe in the guides in the arm 7 so that the upper end of the pipe will enter the seat .2 in the uppermost arm, bringing the air-passage in said pipe into coincidence with the air-passage 21', passing through said arm. The pipe is then clamped in position by means of the clamping-jaws 3 and is then held securely in a vertical position. The length of the pipe is such that the molten glass at the end thereof hangs down within the space inclosed by the mold, so that when the mold is closed the glass will be completely inelosed thereby. The mold is closed by throwing the levern over in the slot m of the arm m. This movement of the levern through the gearing mechanism described will also move the lever to around in line therewith. The inner ends of the levers n and u, with the idle rollers n and u in contact with the bottom of the mold, act to close the mold-halves around the molten glass. By throwing the lever n around into. the position described the stud n on said lever will act to advance the arm m and with it the arm'k. As the arm It has the studs engaging with the annular groove '5 in the clutch-shaft 1?, the movement onthe part of said arm 70 will advance the clutch i into eng'agemcnt with the clutch h. At the same time this is done air is admitted through the gas within the mold. whet thecluteh tom plate which supports them'old, is not;

however, continuous .in one direction, but-the movement is reversed after said bottom plate.

has accomplisheda half of a-revolution. This reversing of the direction of rotationof the bottom plate dis caused by, the action of the cam-disks s. and s. With the cam-disk s ro-.

tatin g in thedirectio'n of the arrow the camface 8 moving in contact with the frictional coner, will act to rotate the shaft p in the di-, rection indicated by the arrow a'-.

, 'impart the rotary movement in one direction This will to the-bottom plate (1; VVhen', however, the

cam-faces of the cam-disk s comes in con-'- tact with the frictional cone '1', the shaft]; will be rotated in the direction of the arrow a.

This will act to reverse the movement of the bottom plate d. This rotation is imparted to the mold in order to prevent the formation of a fin on the lamp-chimneyat the point where the. two halvesof the mold meet. If the rotary action of the mold were continuous in one direction, the neck of the chimney would be twisted and distorted, so that the chimneys v produced would be imperfect; but by impart- .ing a rotary movement in one direction and other compositionlwhich will permit of the revolving of the mold without the sticking of the glass thereto. As soon as the'chimney. has been blown the operator by'throwLg ck then in the other not only is the fin erased, but this twisting of the neck of the article is prevented, so that a perfect chimney without flaws is produced. i-

These'chimneys are blown in what are commonly called 'paste-moldsfsa molds havin g their inner faces coated wlhh paste or the lever n part way with in the slot m throws the clutchiout of engagement with the clutch h and stops the rotation of the mold. At the same time the spring f'forces the mold-halves apart, and the chimney is-removed. By moving the lever n farther within the slot'm until it reaches the-outer end thereof the lever ll is.brought igto the. position shown in'Fig'. It is'of co rseto'be understood that by moving the lever to the-lever n may be oper-.

ated in the same manner.- The movement of the lever n to the position shown in Fig. 3 imparts a. rotary movement to the bevel-gear l", whichmeshcs with the'bevel-gear 'v. This rotation of the bevel-gear '0- raises the arms,

securedthereto,and with it the arm 'vflthro'ugh the connecting-link '0 The partial movem entof the lever uto throw the clutch 11 out of engagement with they clutch it will raise the arm 0 sufficiently to ,bring the latch 00' into engagement with the seat w? on the gear-wheel w. The further movement of the lever/u to the position shown in Fig. .3 will cause further "where blown by hand.

rotationon the partof the bevel-gear v and a further elevation of the arm n. 'The eleva-- tion 'of-the arm 1) when the latch w is in engagement-with the seat w" will act to rotate the gear -..whee1w. 'As said gear wheel w meshes with I the gear-wheel c alike movement is imparted to said last-mentioned gearwheel. This gear-wheelc beingon the shaft into position for blowing,when the operations above described are-repeated. The molds as they pass around in a circle formed by the rotation of the mold-support B pass into'the tank or vessel 0, where they are allowed to cool. I This cooling of the molds is essential where paste-molds are employedin order to prevent the coating from burning out too rapidly..

like articles in quick succession without the employment of skilled labor, while at the same time I am able to produce perfect artil 4 cles in large quantities and at less cost ,than
